extending from the costal margin near the apex to the inner margin slightly above the anal angle, a small 
round spot at the base of the cell, and an elongate spot at the end of it, hyaline-white ; the secondaries 
with a hyaline-white spot at the end of the cell ; the fringe greyish-yellow ; the underside pale yellowish-
